Be'itkno s that I, HERBERT B. TAX-anoint). citizen of the United States, and a resident of the town of Westfield, county of Union,

Light-Signals, of which the following is .a specification. v j This invention relates to an improved, construction and method of operation of light signals. v One object of the'invention is to providea mechanism which will operate to give three indications and which is arranged to nor-v mally givethe danger or stop indication. I A further object is toprovide. a-inechanism Whichis'practically'frictionless in operation. v

Another object is to provide means whereby the mechanism Will give a stop indication upon the failure or" any of the operating mechanism.

Another object of the invention is'to provicl-e means whereby the mechanism is ciead beat in operation to any position.

Further objects will be apparent from the appended description and claims. a V
